British subject, and resident. of, Manchester,

county of Lancaster-,=England,.have invented y The inve'n-tion consists essentially in con structing the machine with (a) one, two or more sets of shafts or spindles at each side, parallelto the longitudinal axis of the machine, the sets ofspindles on the one side being rotated in the opposite directionto the sets of spindleson'. the other, each shaft orspindle being fitted with one or morewings or air blades constructed to adapt themselves. to the angle of resistance to the air which produces the best upward and forward eflect. Means for greatly-accelerating the ve; locityof the wings or air blades during'all or part of their downward rotation. (a)

aring fixed between the prime motor anfihe sets of shafts or spindles so that without interfering with the speed of the motor one of the sets of shafts or spindles can be stopped, or the speed of rotation of thesets of. shafts or spindles on either side of the machine can be, retarded and the speed of the sets of shafts or spindles on the other side correspondingly 35 increased.

The invention will be fully described with reference to the accompanyin drawin Figure 1.- End elevation; ig. 2. Ian.

In carryin out the invention I construct a frame A 0 any suitable light construction in which I mount two sets of shafts or spindles B B carrying wings or air blades C G one set-on each side of the longitudinal axis of the machine indicated by the arrow 012-00. The spindles B and B are'mounted in suitable bearings 22 parallel with the longitudinal axis (ac-a:) of the machine the spindles B on one side being rotated in one direction and the spindles B -on the other B e gearing (i: G are but slightly modified side in the reverse direction. To each of the spindles B B a rigid arm D is attached towards the'forward end of the frame A,

"and an. elastic arm D towards the-rear end of the frame to which sail cloth or suitable materialis attached to form the wings O, O.

The extremity of thearm D is connected with the extremity of the arm D bya wire or bar d. The wings or air blades C C are attached to the arm D tothe spindle or shaft and to thewire d with the back edge adjacent to thearm D free toadjust itself to the wind pressure. The rear arms D are Set at an angle with relation to the forward armsD such that when the arms D are horizontal when moving downward and exercis .ing pressure in'a forward direction the arms- D will have passed the horizontalsand. be

inclined in a downward dlkfiction.

I- prefer to use several spindles B B and wings C G on each side of the machine as shown in Figs. 1 and 2 as I find that by reducing the radius of the wings and in creasing their number the power required to control the machine is very substantially reduced, but if desired a single wing might be used at each side of the machine. The s indles B B are driven from the shafts- E bychains e e. and are geared together by driving chains d atboth endsto rotate simultaneously, the motive power being obtained from any suitable motor and transmitted through the driven wheel F by chain or other gear. The speed of the wings C C is accelerated during all or a portion of their downward movement by any suitable 'construction. of mechanism. The desired acceleration may be brought about by the employ ment of elliptical gearing which will greatly accelerate the speed at one part of the revolution. i

sired acceleration can 2 the obtained while [emplo ing wheels which omcircular. One wheel G of the train of elliptical wheels is on the. shaft H the second elliptical wheel on the shaft H and the third wheel on the shaft 11 The shaft H is divided into three parts h h h the central part h being free to rotate in. either direction. The part h is driven by the elliptical wheels in onedirection and the part [L is driven in the other m loying a train of elliptical direction bya chain from the wheel g on the. shaft H to the wheel g on the," shaft h; a

Anarm K is fixed ou the shaft Ii which en p and h for the purpose 'of reversing the mogages with a corresponding loose arm K on shaft 71; a spriing'lc is' placed between the arm K and the shaft. h to form a bulfer to lessen the shock when the arms meet. A

corresponding arrangement of arms L L and spring Z is fixed between the shafts k tion. The arms K and L areloose npon the central part iz. 'of the shaft-H upon which,

two sliding clutches. M M' are fitted either of which can be thrown into engagement with its respective arm and so convey motion to the shaft h. By'throwi'ng both clutches I M M out ofgear the central shaft may be stopped without stopping the motor. When the clutch M is in engagement with'ithe arm K' the wings'OC are driven toexercise pressure in a forward direction and when the clutch M is in engagement withthe arm L the Wings are driven to e-xercise'pressure in'the rev rse or backward direct'ion- 'The motion is transmitted from the shaft h'by the differential gearing N to the shafts O O E E. The desired acceleration may be.

brought about by the employment of suitable springs which -will greatly accelerate the speed of the driven shaft. The shaft H is] driven from the shaft H-by a sprocket wheel 71 on the shaftH, a sprocket wheel h on the.

shaft H and adrivmg chain k One of the sprocket Wheels preferably the driven Wheel h 'is constructed with .a free wheel '1' action so thatthe shaft H may rotate at a greater speed than the driving shaft H. On

either oneor both ends of the shaft H are. mounted cranks R to which springs S are connected by connecting links or rods .9. On

the upward strokethe spring or springs S are extended and when the crank top center the full effect of the spri g comes .into pla and greatly accelerates the crank on the ownward-stroke. .The springs may bearranged in anyother convenient manner for the same purpose. The motion is transmitted from the shaft H by the differential gearing N tothe shafts O O -E-andE.

The differential gearing consists ofa pinion n which drives a'simila'r pinion-n. .on the line of shaft 0 loose'bevel wheels-n which are mounted on the spindles of a and'gear.

with: the bevel'wheels 0 0. on the shafts O and 0?. The shaft 0 on which the pinion n is fixed is journaled in the ends of the shafts O and O and the arrangement of differential gearing will. drive the shafts O O at a uniform speed when the loads are equal or one shaft slower and theother shaft correspondingly quicker when the'loads are one ual. At the end of shaft 0' a, pair of beve wheels 6 c drive the shaft E at right angles and at the end of shaft 0 a 'pair of bevel wheel 6 6 drive the shaft'E at right n n gles. The shaft E is on the opposite side of the line of shaft 0 to shaft E and is rotated in the opposite direction. The bevel wheels asses theand e are each prov'ided with a brake so that the motion at either side may 'be' reincr'eased, I

In place ,of' the differential gearing the bevel wheels e e? could be driven by clutches. When either clutch is disengaged the-motive power wouldbe-transmitted to the wings ontarded and atthe other side correspondingly clutch still engaged on that. side.

The acceleration of the speed of the wings on the downward part oftheir rotation may be effected in an alternativearrange ment by jointing them to the spindles and holding them in position by springs which .the opposite side of'the machine through the by the rotation of'the spindles are compressed orex'tendedand released at the point atwhich thewings willexercise the greatest downward pressure on the air (therefore ivingg reater velocitylto the wings at-the time of release than. the spindleswvould impart. Or the desired acceleration may be effected by springs or cylinders andpistons in which ,forceis generated or accumulated during a portion of the revolution. of the spindles and released at any desired point to accelerate the speed of the spindles and throu h .them

the wings, in the manner describe inthe specification of'my former. ap lication for patent Serial No; 205,052 file 26th April,

1904."j The mechanism would be operated asfollows :\Vhen thefclutch M is in action the arm K would engage with the arm-K when the wings orair blades were rotating 1n a downward direction and force them-down- V wardswith great rapidity and thepower would beexercised in giving an'upward and forward motion to the machine to which the mechanism was attached. Durin the 1115- Ward rotation ofthe wings. or ,air glades the effect of the train of elliptical wheels would reducethe speed to'a point at which the pressure the wings or air blades'would exercise.
